Hello, Waldo; welcome to the forum.

Thank you for the signal report.



There are some errors in the TVFool signal report because they are using a defective database to generate reports. This report from rabbitears.info has a more accurate list of channels:

What channels did you get and where was the antenna located for the test?

Where will your new antenna be located?

There are several possible solutions. The stronger channels are VHF from 145 degrees and the weaker channels are UHF from 170 degrees.

You could have a UHF/VHF combo antenna like the Winegard HD7694P aimed between 145 and 170, but closer to 170. You wouldn't be able to use a preamp to help the weak CBS because it would be overloaded by KYES. Also, the contact between the forks and the wires from the two sections of the antenna in the 8269 balun housing might be affected by low temperatures.





The solution that I favor would be two separate antennas; a VHF antenna aimed at 145 and a UHF antenna aimed at 170. The two feed lines would come inside, and a medium gain amp (out of the cold weather) could be added to the UHF coax if needed, and the two combined with a UVSJ UHF/VHF combiner.

The simple two antenna solution would be an Antennas Direct DB4e for UHF and the accessory VHF dipole kit for VHF.

If for some odd reason the VHF dipole kit doesn't have enough gain for 7, 8, 10, and 12, substitute a Stellar Labs 30-2475 VHF antenna.
